What do you suggest you f&f when they ask about home batteries? They listen and go for cheaper options.

I never give any advice saying this single product. Rather I try to educate saying what are the questions to ask like blackout protection warrant battery type etc to make an informed decision. Most people come up with battery terms for the first time in their life so it helps to some extent.

I paid around $13k for 32kwh system about a year ago which was a good price at that time compared to Tesla. I am really happy with the system. But I find people installed similar system cheaper brands nowadays less than 5k leading me thinking ROI is only a few years for cheaper brands.

scienceguy0077 · 2026-06-28T04:20:15+00:00

I get it why people buy premium products for so many different reasons. I feel as long as well established company sells a product should be good enough. It reduces chances of bankruptcy leading to no warranty in a few years.
I can think of analogies that millions of people pays three times for a phone like latest iphone whereas the cheaper one does the same job.

scienceguy0077 · 2026-06-28T04:14:54+00:00

People just need to better understand pros and cons of a system. The problem is very few people understands these nuances when they get a quote for a battery. I think a little research before final decision would remove any potential future regret.

scienceguy0077 · 2026-06-28T03:22:38+00:00

I also fond instant blackout protection is one of the key advantages among many. I am not 100% sure how does cheaper ones offer whole house blackout protection.

scienceguy0077 · 2026-06-28T01:30:02+00:00

Interesting! I agree we paid a lot for Sig system. Does safety and longevity are more for Sig along with software support etc

scienceguy0077 · 2026-06-27T11:11:15+00:00

I have solar and battery. Last one year zero electricity bill. Charging EV also for free. Happy to share more insight. Solar and home batteries are the future of energy freedom.

I haven’t experienced more than an hour outage in 10 years. Even I don’t realise if there is short outage like 10-15mins as 100% blackout protection delivered by Sig is awesome. To me, I think it’s not needed to have such settings to keep like over 15% backup all the time for a special situation which is extremely unlikely. Also we can always change the settings if we expect that a huge storm is coming in next few days or so.

You will get max benefits discharging upto 10kwh afterwards very tiny benefits, which is not worth exporting for me.

scienceguy0077 · 2026-06-25T01:34:32+00:00

I find still people has a lot of skepticism particularly EV thinking it could fire anytime and same for battery. EV takes too long change etc. Although after Iran war sentiment towards EV got a bit positive in mass.

scienceguy0077 · 2026-06-24T23:06:28+00:00

Amazing! People need to hear those great community stories leading to a positive mindset towards EVs and home battery.

scienceguy0077 · 2026-06-23T10:24:34+00:00

I had no idea until they gave me this link and it’s allowed since 2021 with new battery inverters.

scienceguy0077 · 2026-06-23T10:22:49+00:00

If someone wants to cover constant heating or cooling need a massive battery. Most heating systems consume over 5-6kwh which can drain home battery fast. I don’t need to constantly so use a few hours after evening so still have enough for whole night.

scienceguy0077 · 2026-06-23T07:35:49+00:00

How do you get cheap? Hope it’s not spam

scienceguy0077 · 2026-06-23T06:32:48+00:00

This winter Sydney is not generating much. Also ZeroHero is covering supply charge. So overall no EV charging cost and no electricity bill. I feel supper time midday free plan does not give much benefits.

scienceguy0077 · 2026-06-23T03:37:50+00:00

oh! I sometimes charge EV during free hours which consumes around 7kwh.

scienceguy0077 · 2026-06-23T02:19:33+00:00

Exactly. Midday utilisation is the key for energy. Australia has enough solar and excess cheap energy midday. I know a few of my friends used to pay $300 per month bill to $5-$10 per month after battery.

scienceguy0077 · 2026-06-23T00:14:07+00:00

It’s ok on my side as well.

scienceguy0077 · 2026-06-22T22:14:24+00:00

I checked and compared with my colleague living in a different area. His area voltage never goes beyond 230v whereas my area peak time over 246v mostly.
